Building a python Api for hydra-ledger blockchain using Maturin and Rust wasm

• Rust
• Maturin
• Python > 3.8

Enter the base directory of the project and activate the virtual environment with the following command and install the required python packages.

source env/bin/activate
pip install -r requirements.txt

To compile the code, you can run the following command. This command builds a python wheel for the rust code.

maturin develop

hydra.py contains a module that interacts with the hydra testnet. To use the module, you can import the HydraWallet class from api/hydra.py.

from hydra import HydraWallet, HydraChain

A example method that verifies a signed statement can be found in the module

chain = HydraChain()
signed_statement =  {
    "signature": "00987890098776556667788976676787655"
    "claim": {
    "subject": "did:morpheus:ezbeWGSY2dqcUBqT8K7R14xr",
    "content": {}...},    
    }
result = chain.verify_signed_statement(signed_statement)
print(result)
>>> True

To spin up the wallet application run the command below in the base directory

python3 app.py
